Abstract

Wind is moving air caused by the earth's rotation and also because of the difference in air pressure around it. The wind flows that occur include laminar flow and turbulent flow. Judging from the effect of spreading its direction, the wind that passes through a building, its flow will split into horizontal and vertical axes and pass along the geometry and structure of the building. This happens because the wind speed increases due to the increased wind pressure along the side of the building. Departing from this hypothesis, this research was conducted to compare the velocity potential on the angle side of the building roof with the speed at the top of the building (Rooftop) as a starting point for the development of new renewable energy engineering, especially wind energy. This experiment was conducted at the Dean Building of the Faculty of Engineering, Sultan Ageng Tirtayasa University, Cilegon, Banten. After conducting experiments with reference to the International Electrotechnical Commission (IEC) 61400-12-1 standard, this research found that on the angle side of the building the average and maximum velocity are higher than those on the roof of the building, also the wind energy potential is higher, amounting to ≥20.94%. In terms of Daily Wind Energy Potential, the elbow side of the building is proven to be more efficient with an increase in efficiency of 42.2%.

Abstract

Sultan Wind Turbine is a vertical type wind turbine researched by New Renewable Energy Lab which is used as development for wind energy utilization. In this wind turbine, there are problems in the form of blade resistance which is not strong enough to withstand wind velocity when the wind blows reaches 4 m/s. The blade, which is one of the parts that have the highest liability on the turbine, can be improved in terms of performance and their overall strength. The blade material which currently used is fibreglass, and Styrofoam can be substituted using a better material to improve its performance. Carbon fiber and ABS filament can be substituted as a blanket and airfoil to be used as materials for manufacturing new blades. This research will focus on improvised blades in terms of performance and strength. With an experimental and quantitative approach, the data obtained from the blades that have been improvised with carbon fiber and ABS filament, resulting in blades that are superior from their predecessors.

Abstract

With the decrease in world oil reserves, energy savings have begun to be launched in almost all countries of the world. Indonesia has now become one of the crude oil importing countries, so efforts are needed to reduce dependence on oil and gas fuels. The sustainability of biomass gasification technology, especially in Indonesia, is highly guaranteed because of the abundant availability of biomass in Indonesia. The purpose of this study is to determine the performance of a 5 kW diesel generator against variations in loading with diesel fuel. The second is to know the performance of a 5 kW diesel generator against variations in loading with diesel fuel and rice husk syngas. Data collection on the performance characterization of the 5 Kw diesel generator set from syngas rice husks against variations in loading was carried out at the New Renewable Energy Engineering Laboratory. The loading carried out in this study was using a 5200 Watt halogen lamp. The power used in this study is only up to a maximum of 3200 Watt. The test result shows that the power generated by the generator is greater when using diesel fuel compared to using a mixture of diesel fuel with syngas. The value of the generator power for each loading variable increased when using low electrical load and decreasing when using high electrical load.

Abstract

Flow Visualization is the process of making the physical flow of a fluid visible. The air fluid used is transparent, so the flow pattern must be shown by several special methods. There are three methods for visualizing flow: surface flow visualization, particle tracking method, and optical method. Turbulence is one of the most important subjects related to testing the test section in a wind tunnel, at different wind speeds turbulence levels and other flow quality parameters must be kept as close as possible to free flow conditions. The flow visualization test is carried out using a slow motion camera at speeds of 1 m/s, 2 m/s, 3 m/s, 4 m/s and 5m/s which will form a fluid flow in the form of lines of smoke coming out of the nozzle holes inside. Test section. From the research results, the authors can conclude that the flow obtained forms a laminar flow and good suction power from various wind speed variables.

Abstract

One of the methods to increase the efficiency of wind turbines is to add directional fins so that the wind turbine faces and is in the same direction as the wind. The use of triangular fins will slightly increase the performance of wind turbines compared to rectangular and trapezoidal shapes. The most crucial factor is that the fin area is not less than 5% of the swept area on the turbine blades. And according to calculations and simulation data, the convex pentagonal shape generates the greatest power. While the tests conducted by P.R. Ebert et al, that a twin wing with a high wing angle shows a greater damping response than a single wing. The aim of this research is to optimize the performance of the Sultan V-4.5 wind turbine by adding guide fins. Simulation methods and design of directional fins were carried out to obtain the most suitable fin shape and size. By using an aspect ratio of 1.4, the distance from the center of gravity to the center axis of the turbine is reduced. Performance tests were carried out using fins with areas of 0.06 m2, 0.12 m2 and 0.22 m2. Twin fins are used, with a 30o angle between them, to reduce the oscillatory forces resulting from wind motion. Fin profiles with maximum force when exposed to wind at angles of 0°, 5°, 10°, 15°, 20°, 25°, and 30° were selected from the available profiles using Computer Fluid Dynamic analysis. To determine the most suitable structure and material for fins, simulate the topology optimization and material selection used. According to his findings, the isosceles and right-angled triangles, which produce forces of 0.91 N and 0.77 N respectively, are the strongest. PVC plates are the materials used. The results of this study indicate that 2 m/s wind speeds frequency, the type 3b fin designs are the best design according to performance tests. The end result, coefficient of power increases and power generates increases respectively 5 and 3.8 times the previous research.

Abstract

One of the problems encountered by a laboratory with a small-scale wind tunnel facility is that the wind tunnel can only produce limited wind speed to simulate fluid behavior that passes through a tested object. This problem caused the laboratory to be unable to analyze fluid behavior that passed through a tested object. In that case, scale modeling to analyze fluid behavior at a certain speed without having to reach the actual speed is needed. The purpose of this research is to prove the passive grid addition effect on turbulence in a small-scale wind tunnel. The test is done by capturing smoke movement through the test section with and without a grid. Then analyze the collected data with SynthEyes software. The wind speed variation used in this research is between 0.5 and 6.0 m/s. The result of this research is that the smoke flow characteristic in a wind tunnel without a grid tends to be laminar flow, and the smoke flow in a wind tunnel with a grid tends to be turbulence flow. Smoke flow characteristics with a grid are still too far from smoke flow characteristics without a grid with the highest speed variation.

Abstract

In the current era, the development of science in all aspects continues to change. The use of wind at this time is necessary for the efficiency of the energy used. The wind speed research method for this study utilizes experimental laboratory methods, specifically employing a Pitot tube measuring instrument to collect wind speed data. From the wind speed data obtained using a frequency of 25–50 Hz, there is only a slight difference between readings from a testometer with a pitot tube and only at frequencies of 39 Hz and 43 Hz, which have a visible difference. The graph indicates that the research was successful by comparing the readings on the testometer.
